Waterwheel pit remains ?
Wheal Castle, Boswedden Mine, Kenidjack Valley, St Just, Cornwall, England, UK
This looks like a waterwheel pit remain and can be seen at the base of the Wheal Castle dump. The little stream, the Tregaseal river, separating the Wheal Castle and Boswedden setts is on the right hand. Picture taken by Claire de Coen, on 19 may, 2011.
